CDT Series LQC, Liquid Cooling CDU Quick Disconnects

CDT Series Quick Disconnect Couplings for Data Center Liquid Cooling

Parker's CDT Series Quick Disconnect (QD) Couplings are engineered specifically for data center liquid cooling systems, delivering reliable, leak-free fluid connections for high-density computing environments. Developed in collaboration with the Open Compute Project (OCP), the CDT Series is fully compliant with LQC V2 performance and testing specifications, ensuring interoperability with other OCP-approved Large Quick Connect (LQC) manufacturers.

Designed for use in servers, rackable server systems, cooling distribution units (CDUs), and supercomputing applications, CDT Series couplings feature a threaded connection design that provides mechanical advantage for connecting under pressure. The advanced flat-face valve technology automatically seals during disconnection to prevent fluid loss, helping protect sensitive electronic equipment and maintain system uptime.

Manufactured from high-quality stainless steel, CDT couplings are available in multiple port configurations to support rack manifolds, flexible cooling hoses, and a variety of liquid cooling architectures. Each coupling is assembled and tested in a clean room environment and undergoes helium leak testing to ensure exceptional quality, reliability, and contamination control.
